■

Conditions under which the 

system will not detect a vehicle

The RCTA function is not designed 

to detect the following types of vehi-

cles and/or objects:

●

Vehicles approaching from directly 

behind

●

Vehicles backing up in a parking 

space next to your vehicle

●

Vehicles that the sensors cannot 

detect due to obstructions

●

Guardrails, walls, signs, parked 

vehicles and similar stationary 
objects

*

●

Small motorcycles, bicycles, 
pedestrians, etc.

*

●

Vehicles moving away from your 

vehicle

●

Vehicles approaching from the 

parking spaces next to your vehi-
cle

*

●

The distance between the sensor 

and approaching vehicle gets too 

close

*

: Depending on the conditions, 

detection of a vehicle and/or 
object may occur.

■

Situations in which the system 

may not operate properly

The RCTA function may not detect 

vehicles correctly in the following 

situations:

●

When the sensor is misaligned 

due to a strong impact to the sen-

sor or its surrounding area

●

When mud, snow, ice, a sticker, 

etc.,is covering the sensor or sur-

rounding area on the rear bumper

●

When driving on a road surface 

that is wet with standing water 

during bad weather, such as 

heavy rain, snow, or fog

●

When multiple vehicles are 

approaching with only a small gap 

between each vehicle

●

When a vehicle is approaching at 

high speed

●

When equipment that may 

obstruct a sensor is installed, such 

as a towing eyelet, bumper pro-

tector (an additional trim strip, 

etc.), bicycle carrier, or snow plow

●

When backing up on a slope with 

a sharp change in grade

angle parking spot

●

Immediately after the RCTA func-

tion is turned on

●

Immediately after the fuel cell sys-

tem is started with the RCTA func-

tion on

●

When the sensors cannot detect a 

vehicle due to obstructions

●

When towing a trailer

●

When there is a significant differ-

ence in height between your vehi-

cle and the vehicle that enters the 

detection area

●

When a sensor or the area around 

a sensor is extremely hot or cold

●

or lowered due to the carried load

●

When turning while backing up

●

When a vehicle turns into the 

detection area

■

Situations in which the system 

may operate even if there is no 

possibility of a collision

Instances of the RCTA function 

unnecessary detecting a vehicle 

and/or object may increase in the 

following situations:

●

When the parking space faces a 

street and vehicles are being 

driven on the street

●

When the distance between your 

vehicle and metal objects, such as 

a guardrail, wall, sign, or parked 

vehicle, which may reflect electri-

cal waves toward the rear of the 

vehicle, is short

●

When equipment that may 

obstruct a sensor is installed, such 

as a towing eyelet, bumper pro-

tector (an additional trim strip, 

etc.), bicycle carrier, or snow plow

RCD (Rear Camera 

Detection)

*

When the vehicle is backing 
up, the rear camera detec-
tion function can detect 
pedestrians in the detec-
tion area behind the vehicle. 
If a pedestrian is detected, a 
buzzer will sound and an 
icon will be displayed on 
the multimedia display to 
inform the driver of the 
pedestrian.

WARNING

■

Cautions regarding the use of 

the system

The recognition and control capa-

bilities for this system are limited.
The driver should always drive 

safely by always being responsi-

ble without over relying on the 

system and have a understanding 

of the surrounding situations.

■

To ensure the system can 

operate properly

Observe the following, otherwise 

there is the danger that could lead 

to an accident.

●

Always clean the camera with-

out damaging it.

●

Do not install market electronic 

parts (such as Illuminated 

license plate, fog lamps, etc.) in 

the camera vicinity.

●

Do not subject the camera vicin-

ity to strong impacts. If the vicin-

ity is subjected to a strong 

impact, have the vehicle

■

Situations in which the system 

may not operate properly

●

Some pedestrians, such as the 

following, may not be detected by 

the rear camera detection func-

tion, preventing the function from 

operating properly:

• Pedestrians who are bending for-

ward or squatting

• Pedestrians who are lying down

• Pedestrians who are running

• Pedestrians who suddenly enter 

the detection area

• People riding a bicycle, skate-

board, or other light vehicle

• Pedestrians wearing oversized 

clothing such as a rain coat, long 

skirt, etc., making their silhouette 

obscure

• Pedestrians whose body is par-

tially hidden by an object, such as 

a cart or umbrella

• Pedestrians which are obscured 

by darkness, such as at night

●

In some situations, such as the 

following, pedestrians may not be 

detected by the rear camera 

detection function, preventing the 

function from operating properly:

• When backing up in inclement 

weather (rain, snow, fog, etc.)

• When the rear camera is 

obscured (dirt, snow, ice, etc., are 

attached) or scratched

• When a very bright light, such as 

the sun, or the headlights of 

another vehicle, shines directly 

into the rear camera

• When backing up in a place where 

the surrounding brightness 

changes suddenly, such as at the 

entrance or exit of a garage or 

underground parking lot

• When backing up in a dim envi-

ronment such as during dusk or in 

an underground parking lot

• When the camera position and 

direction are deviated

• When a towing hook is attached

• When water droplets are flowing 

on the camera lens

• When the vehicle height is 

extremely changed (nose up, 

nose down).

• When tire chains or an emergency 

tire puncture repair kit is used

• If the suspension has been modi-

fied or tires of a size other than 

specified are installed

• If an electronic component, such 

as a backlit license plate or rear 

fog light, is installed near the rear 

camera

• If a bumper protector, such as an 

additional trim strip, is installed to 

the rear bumper

■

Situations in which the system 

may operate unexpectedly

●

Even though there are no pedes-

trians in the detection area, some 

objects, such as the following, 

may be detected, possibly caus-

ing the rear camera detection 

function to operate.

• Three dimensional objects, such 

as a pole, traffic cone, fence, or 

parked vehicle

• Moving objects, such as a car or 

motorcycle

• Objects moving toward your vehi-

cle when backing up, such as 

flags or puddles (or airborne mat-

ter, such as smoke, steam, rain, or 

snow)

• Cobblestone or gravel roads, tram 

rails, road repairs, white lines, 

pedestrian crossings or fallen 

leaves on the road

• Metal covers (gratings), such as 

those used for drainage ditches

• Objects reflected in a puddle or on 

a wet road surface

• Shadows on the road

●

In some situations, such as the 

following, the rear camera detec-

tion function may operate even 

though there are no pedestrians in 

the detection area.

• When backing up toward the road-

side or a bump on the road

• When backing up toward an 

incline/decline

The Parking Support Brake 
system consists of the fol-
lowing functions that oper-
ate when driving at a low 
speed or backing up, such 
as when parking. When the 
system determines that the 
probability of a collision 
with a detected object or 
pedestrian is high, a warn-
ing operates to urge the 
driver to take evasive 
action. If the system deter-
mines that the possibility of 
a collision with a detected 
object or pedestrian is 
extremely high, the brakes 
are automatically applied to 
help avoid the collision or 
help reduce the impact of 
the collision.

WARNING

■

Cautions regarding the use of 

the system

Do not overly rely on the system, 

as doing so may lead to an acci-

dent.
Always drive while checking the 

safety of the surroundings of the 

vehicle.
Depending on the vehicle and 

road conditions, weather, etc., the 

system may not operate.
The detection capabilities of sen-

sors and radars are limited. 

Always drive while checking the 

safety of the surroundings of the 

vehicle.

●

The driver is solely responsible 

for safe driving. Always drive 

carefully, taking care to observe 

your surroundings. The Parking 

Support Brake system is 

designed to provide support to 

lessen the severity of collisions. 

However, it may not operate in 

some situations.

●

The Parking Support Brake sys-

tem is not designed to stop the 

vehicle completely. Additionally, 

even if the system has stopped 

the vehicle, it is necessary to 

depress the brake pedal imme-

diately as brake control will be 

canceled after approximately 2 

seconds.

●

It is extremely dangerous to 

check the system operations by 

intentionally driving the vehicle 

into the direction of a wall, etc. 

Never attempt such actions.

■

When to disable the Parking 

Support Brake

In the following situations, disable 

the Parking Support Brake as the 

system may operate even though 

there is no possibility of a colli-

sion.

●

When inspecting the vehicle 

using a chassis roller, chassis 

dynamo or free roller

●

When loading the vehicle onto a 

boat, truck or other transport 

vessel

●

If the suspension has been 

modified or tires of a size other 

than specified are installed

●

If the front of the vehicle is 

raised or lowered due to the 

carried load

●

When equipment that may 

obstruct a sensor is installed, 

such as a towing eyelet, bumper 

protector (an additional trim 

strip, etc.), bicycle carrier, or 

snow plow

●

When using automatic car 

washing devices

●

If the vehicle cannot be driven in 

a stable manner, such as when 

the vehicle has been in an acci-

dent or is malfunctioning

●

When the vehicle is driven in a 

sporty manner or off-road

●

When the tires are not properly 

inflated

●

When the tires are very worn

Intuitive parking assist buzzer

Regardless of whether the Intuitive 

parking assist buzzer is enabled or 

not, if the PKSB (Parking Support 

Brake) system is enabled, the front 

or rear sensors detect a static object 

and brake control is performed, the 

Intuitive parking assist buzzer will 

sound to notify the driver of the 

approximate distance to the object.

If the sensors detect a static 
object, such as a wall, in the 
traveling direction of the 
vehicle and the system 
determines that a collision 
may occur due to the vehi-
cle suddenly moving for-
ward due to an accidental 
accelerator pedal operation, 
the vehicle moving the 
unintended direction due to 
the wrong shift position 
being selected, or while 
parking or traveling at low 
speeds, the system will 
operate to lessen the impact 
with the detected static 
object and reduce the 
resulting damage.
